If you enter the hall with a level 20 animal companion, you can display a generic pet statue at this monument, which features a bear, a Lynx, and a wolf. (You can only do this once per character.) In addition, you can display statues for three other animals (if you bring them individually to the hall), each of which counts towards the Any Rare Pet Statue requirement for the rewards calculator.

You cannot display pets of your heroes; however, in the Zaishen Menagerie, you can show a hero pet to Emryd the Tamer, ask Wynn to spawn the same animal, and you can charm the pet she releases without disposing of your hero's pet. Then you can take your newly charmed pet to the hall for dedication.

Heroes can be included in the monument at any level as long as they have received either of their Hero Armor upgrades.

M.O.X. can be displayed as soon as it is acquired, since the golem's armor cannot be upgraded.

Once a hero statue has been added to the Hall of Monuments that hero cannot be added again, even if different hero armor is obtained.

As with any of the monuments, you can dedicate the statues using a combination of characters on your account or using just one character.
